SoftToO |
2025QH16 |
ALIh310091 - ALIh310108 |
Observed with seeing fluctuating around 1.0''. The OB was done in two parts, since the script
was started right before midnight which caused an error in the hitandrun script and needed to
be restarted with a new timestamp. |

Attempted multiple times, but exposures yielded wonky star lines and the comet was not visible in the frames. |

ALIi240077 - ALIi240097 |
11 exposures of 300s obtained with 2 OB executions - resetting after 9th exposure during the first run.
Both science target and the std. star observed through thin clouds and with seeing just below 1 arcsec. |

Observations failed due to tcs.asteph command not being able to compute the orbit. The provided commands were syntactically correct, but the script itself could not carry out the calculations. The error log is long and we unfortunately can't copy-paste from out observing system, but please let me know if a reproduction of the error messages would help. The most prominent errors are regarding "initial orbit not available" and "no sample orbits found". Last message:
"No orbit could be found, nothing much can be done. Abort observations." |

The above information is collected from the ToO/Mon reports that have been created by the observer.
Should any of the observations have been carried out using the OB system, you will find additional information
